Earthquake and Postearthquake Fire Testing of a Midrise Cold-Formed Steel-Framed Building. II: Shear Wall Behavior and Design Implications
Publisher: ASCE
Abstract: Complementing a companion paper that summarizes the building global response and physical damage of a midrise cold-formed steel (CFS) framed building during an earthquake and postearthquake fire test program, this paper ...
Sensitivity of Shallow Foundation Response to Model Input Parameters
Publisher: American Society of Civil Engineers
Abstract: From a predictive point of view, it is desirable to characterize the effect of varying model input parameters on the seismic response of soil-foundation systems. In this paper, this issue is studied for shallow foundation ...
Assessment of Gas Leakage Rates through Damaged Reinforced-Concrete Walls
Publisher: American Society of Civil Engineers
Abstract: The increased permeability that develops in damaged concrete walls translates directly to increased leakage of gases through the wall. For reinforced concrete structures housing dangerous gases, it is important to evaluate ...
Experimentally Measured Permeability of Uncracked and Cracked Concrete Components
Publisher: American Society of Civil Engineers
Abstract: In this paper, the relationship between concrete damage and air flow is evaluated using model-scale reinforced concrete walls. The focus is on the walls behavior under uniaxial and biaxial loading conditions. The method ...
Flexural Strength and Ductility of Extended Pile-Shafts. II: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: Results of an experimental program investigating the lateral strength and ductility capacity of reinforced concrete piles are presented. Four full-scale reinforced concrete piles with details representative of the current ...
Fragility of Bench-Mounted Equipment Considering Uncertain Parameters
Publisher: American Society of Civil Engineers
Abstract: This paper presents analytically developed seismic fragility curves for unattached bench-mounted equipment considering representative building, bench, and equipment interface properties. The emphasis of the study is on ...
Design-Oriented Model for Capturing the In-Plane Seismic Response of Partition Walls
Publisher: American Society of Civil Engineers
Abstract: Using data generated from experiments, a numerical model is developed for capturing the in-plane seismic response of full-height cold-formed steel framed partition walls. The behavior of the partition wall is captured using ...
Improved Image Analysis for Evaluating Concrete Damage
Publisher: American Society of Civil Engineers
Abstract: The use of images, whether in routine maintenance, or postearthquake reconnaissance, has quickly become the preferred approach to record and archive the exterior damage of existing infrastructure. Postsurvey analysis of ...
Urban Damage Estimation Using Statistical Processing of Satellite Images
Publisher: American Society of Civil Engineers
Abstract: Remotely sensed satellite imagery of an earthquake-affected region can significantly assist in estimating the severity of infrastructure damage. Modern high-resolution satellite systems have been launched to provide users ...
Simulation of Full-Scale Cyclic Lateral Load Tests on Piles
Publisher: American Society of Civil Engineers
Abstract: The hysteretic global and local response of reinforced concrete pile shafts is studied herein using a commonly adopted finite-element (FE) analysis approach with nonlinear fiber beam–column elements for the piles and nonlinear
